Patented Oct. 4, 1932 UNITED STATES PATENT OFFICE MALCOLM G. CARY, OF BALTIMORE, MARYLAND, ASSIGNOR TO WESTERN ELECTRIC COMPANY, INCORPORATED, 015 NEW YORK, N. Y., A CORPORATION OF NEW YORK GOILING APPARATUS Application filed August 27, 1930. Serial N0. 478,052.

This invention relates to a coiling apparatus and more particularly to an apparatus for coiling wire.

An object of theinvention is to provide a coiling apparatus which will be simpleand g ing rubber covered wire, of a centrally pivcompact in construction, and eflicient and economical in operation.

'One'embodiment of the invention contemplates the provision, in an apparatus for coiloted 'arm having a coiling spool rotatably mounted at each end, a clutch portion being connected to each spool. The arm is freely rotatable to bring one of the spools to a loadis ing station where the arm is locked in position and the clutch portion engaged to drive the spool by a foot treadle-operated system of gears and levers, the spool on the other end being free to permit the coil to be tied,

2'6 tagged and removed.

The invention will be more fully understood by reference to the following detailed description, read in connection with the accompanying drawings forming a part there- 2 5 of, in which Fig. 1 is a fragmentary plan view, partly in section, of an apparatus embodying the invention and Fig. 2 is a fragmentary front elevation to thereof.

Referring tothe drawings, wherein similar parts are indicated by ldentlcal reference numerals, a wire coiling'apparatus, generally v desi ated by the numeral 10, includes a foundation or base 11 upon the front of which is secured an upright pedestal 12 which is surmounted by a bearing 14 secured thereto. A

' shaft 15, mountedin the bearing, supports a freely rotatable arm 16, in opposite ends of cured upon the rotatable shaft18 and having a plurality of spaced radially projecting arms 23, in the present instance six arms being employed. At its extremity each arm terminates in a concavely curved finger 24 which is provided at its base with a pair of parallel ledges 26 which project from the arms. Each of these ledges is provided with an aperture 27 which is concentric with the corresponding aperture on the other ledge and contains a pin 28. A second concavely curved finger 30, having at the base thereof a perforated fin 31, is mounted adjacent to the finger 24 to be complementary thereto in forming a recess by placing the fin 31 between the ledges 26 and extending the pin 28 through the fin to permit the finger 30 to be rotatable with respect to the finger 24. At the base of the fin 31 a projection 32 is formed to which is pivotally secured an elongated link 34 to which, in turn, is pivotally secured a collar 35 which surrounds and is slidable upon the shaft 18. The collar is provided with an external knob 36 by means of which the collar may be caused to slide upon the shaft 18 whereupon the link 34 is carried to cause the finger 30 to rotate. 'A. recess 38 is formed in the end of the shaft 18 and a spring 39 is mounted therein, the spring engaging the knob 36 and tending to maintain the finger 30 in closed position. In order to permit the projection 32 to pass therethrough when the knob 36 is pressed to open the finger 30, a slot 40 is provided in the arm 23 adjacent thereto. A clutch portion 42 is secured to the rear or opposite end of the shaft 18.

Mounted upon the base 11 and to the rear of pedestal 12 (Fig. 1) is a motor 43 of any suita-ble'character by which is driven a shaft 44 which extends from the motor into a gear box 46 in which may be mounted suitable bevel gears (not shown) for connecting a drive shaft 47 with the shaft 44. A sleeve 48 isslidably keyed upon the shaft 47 and is formed with a clutch member 50 secured thereto. The clutch member 50 is peripherally grooved to receive a freely rotatable band 51 upon which is secured a projecting pin 52.

A bell crank lever 54 secured to the top of a vertical shaft 55 mounted in the base, is

hitheb f ir am 5 u in n' 'pp e direction. A pedestal 62 mounted upon the base 11 at the front thereof and positioned opposite to the arm 16 is formed with a horizontal aperture 63 (Fig-.2) in which is slidably mounted an elongated latch member 64. At eachend ofthe arm 16 anaperture 66 is formed for the purpose of receiving the latch member 64 to lock the arm in stationary position. shoulder 67 on which is seated a coil spring 68 which-extends in a tubular aperture 70 'in the pedestal 62. At the opening of the. aperture'ZO a threadedicollar 71 is mounted in which is adjustably'secured threaded keep-,

er bolt 72 by means of which the tension in the spring '68 may be suitably regulated.

' The latch 64 is surmounted with a pin 7 which is engaged by the bifurcated arm 61 of the lever 60. A horizontal shaft 75 extends from the base, being journalled in a supporting bracket 76 which is bolted to a I stationary shield 84 in front of the apparatus.

' bottom of: the vertical shaft 55.

A foot treadle 7 8 is suitably keyed to the frontend ofthe shaft 75 andis adapted when moved to-rotate a bevel gearTQlreyed to the rear end of the shaft 75, which gear meshes with a bevel' gear8O secured to the V A bracket 8211s suitably secured on the shield 84 above the treadle 78 and is connected with the latter by means of a spring 83, the purpose of which is to yieldably'maintain the treadle 78 in itsupperinost position, shown in full lines in Fig. 2. The stationary shield 84 extends from the ground to the level of the arm 16 and. is provided at its upper edge. with a horizontal rod 86 to which is hingably se-.

cured a semi-circular cover 87.: The cover is providedwith a handle 88, of anysuitable typewh'ereby the cover may be raised or lowered about the rod 86. To the left of the machine and above the arm 16, the'cover'is provided'with aslot 89 which permits a wire strand 90to pass within the cover to the coilinghead. The stationary'shield'84 is provided at the bottom thereof with an aperture 91 for affording access to'the treadle 78. A stationary concave guard 92 of any suitable [type is secured in front of the base and immediately to the right of the shield 84 by a I bolted bracket '93, and is provided with an upper opening 94 through which the coiling head moves as it is rotated vertically by the arm 16. The bracket may be com- 1 posed of any suitable bar or strap material,

The latch 64 is provided with aand is secured to the front end of the shaft 15.

In considering the mode of operation of the abovedesoribed apparatus, it will be understood that, in normal practice, the time required by a skilled operator to bind the wire coiled upon a coiling head when'full-y' loaded,

to apply a proper identifying tag or tags theretoand remove the bundle of coiled wire from the coiling head isroughly equivalent to-the time required to completely load an empty coiling head. Byusing the embodiment described, the services of only one attendant are required, for the binding, tagging and removing operation may be conducted from the front of the machine or in other words, from the sameside of theapparatus as that from which the operation of the driven coiling head is controlled, thus permitting the full output of the machine to be secured through the efforts ofa single attendant.

. The normal position of the curved portion 80 is as shown in the coiling head at the loading station on the left in Fig. 1, wherein it will be, noted the concavities of the fingers 24 and 30 form a recess in'which thewire 90 may be wound. To load the ceiling head'the cover 87 is raised, the treadle 78iis maintained in its uppermost position by the spring 83 and the bell crank levers 56 and 6l are in the positions indicated in full lines in Fig. 1, whe rein the clutch portions 42 and are engaged to drive one coiling head from the shaft' 47, and the spring 68 effective to maintain' the latch member 64 within the terminal recess 66 of the arm 16. ;When the coiling head is filled or when any desired lesser amount of wire has been coiled thereon and it is desirable. to cease winding, the operator presses the treadle 78 downwardly, as shown in dotted lines in Fig. 2, against the tension of the spring 83, rotating the vertical shaft through the bevel gears-79 and 80. The bell crank lever 54 is thus thrown in a counterclockwise direction, as shown in dotted lines in Fig. 1,

to. disengage the clutchmember 50 from the clutch portion 42 and stop the rotationof the coiling head, and the bell crank lever 61 is rotated in a clockwise directionabout the pin 57 in order to withdraw, the latch mem-.

ber 64 from'the recess 66. The wire 90 is cut and withdrawal of the latch causes the arm 16 to rotate in a counterclockwise direction as indicated by thearrow in Fig; 2 upon the shaft 15, due to the weight of the wire 90 upon the loaded head. The rotation; of the arm 16 is assisted through an angle of 180 manually 'bythe operator, the'empty coiling head on the opposite end thereof being carried upwardly in a counterclockwise direction and then downwardly to be engaged by the latch 64 and clutchmember 50, which operations take placeby reason of the tension of the spring 83 upon the treadle 78 which brings the treadle to its normal upper position when the operator lifts his foot therefrom. The wire entering through the slot 89 is secured to the empty coiling head and the latter is rotated in a clockwise direction from the motor 43, and the coiling of wire upon the second head ensues in the manner described above. As soon as the winding has been properly started on the empty reel, the cover 87 is raised into guarding position and the operator proceeds to remove the coil from the loaded coiling head. This is accomplished by properly tying the bundle with cord and aflixing suitable identifying tags thereto for marking same during its subsequent use. The operator then presses the knob 36, forcing the collar 35 along the shaft 18 against the pressure of the spring 39, thus rotating the curved portions 30 downwardly to the position indicated in Fig. 1, whereupon the bundle of coiled wire may be easily lifted from the head, the tension of the spring 39 acting to return the collar 85.

Substantial economies in time and labor have accompanied use of the described appa ratus, due to the simple and convenient construction wherein the arm and two coiling heads supported thereon are mounted upon one side of the machine during their entire operation, thus permitting perfect control of the machine by one operator during both the winding and tying, tagging and removing operations, and a corresponding saving in time and labor.

What is claimed is:

1. In a wire coiling apparatus, a centrally pivoted arm on one side of the apparatus, the arm being provided at each end with a rotatable coiling head and a recess, a spring pressed latch member for engaging in the recess to render the arm stationary, a driving shaft extending to the other side of the apparatus and having a clutch member secured thereto, a clutch portion on one of the coiling heads and adapted when the arm is stationary to be engaged with the clutch member of the driving shaft, means comprising a pair of bell crank levers for simultaneously disengaging the latch member and the clutch member and a shielding member enclosing the driven coiling head.

2. In a wire coiling apparatus, a centrally pivoted arm on one side of the apparatus, the arm being provided at each end with a rotatable coiling head and a recess, a spring pressed latch member for engaging in the recess to render the arm stationary, a driving shaft extending to the other side of the apparatus and having a clutch member secured thereto, a clutch portion on each coiling head and adapted when the arm is stationary to be engaged with the clutch member of the driving shaft, and a treadle operated rotatable shaft upon which is secured a pair of bell crank levers for simultaneously disengaging the latch member and the clutch member.

In witness whereof, I hereunto subscribe my name this 20th day of August, A. D. 1930.
